So basically what we know is that the autostart rom is looking
for the Disk II or 5.25 drive controller, which are primarily the
same thing other than that one has 20 pin IDC headers and the
other has the DB19 Or is it DE19 connector. Once found it will
attempt to boot from it. I find that I can wait for several minutes
and insert a floppy and it will still be attempting to load it. ;-)

Yes, I found this out. Also System Utilities 3.1 is best for looking
for the volumes on the various drives.

I have every ProDOS version from 1.0 on up and 2.0.3 is the
best. Thanks.

Whatever, as long as they work. ;-)
